+# 商品识别
+
+商品识别技术,是现如今应用非常广的一个领域。拍照购物的方式已经被很多人所采纳,无人结算台已经走入各大超市,无人超市更是如火如荼,这背后都是以商品识别技术作为支撑。商品识别技术大概是"商品检测+商品识别"这样的流程,商品检测模块负责检测出潜在的商品区域,商品识别模型负责将商品检测模块检测出的主体进行识别。识别模块多采用检索的方式,根据查询图片和底库图片进行相似度排序获得预测类别。此文档主要对商品图片的特征提取部分进行相关介绍,内容包括:
+
+- 数据集及预处理方式
+- Backbone的具体设置
+- Loss函数的相关设置
+
+
+## 1 Aliproduct
+
+### 1 数据集
+
+
+
+Aliproduct数据是天池竞赛开源的一个数据集,也是目前开源的最大的商品数据集,其有5万多个标识类别,约250万训练图片。相关数据介绍参考[原论文](https://arxiv.org/abs/2008.05359)。
+
+### 2 图像预处理
+
+- 图像`Resize`到224x224
+- 图像`RandomFlip`
+- Normlize:图像归一化
+
+### 3 Backbone的具体设置
+
+具体是用`ResNet50_vd`作为backbone,主要做了如下修改:
+
+ - 使用ImageNet预训练模型
+
+ - 在GAP后、分类层前加入一个512维的embedding FC层,没有做BatchNorm和激活。
+
+
+### 4 Loss的设置
+
+在Aliproduct商品识别中,使用了[CELoss](../../../ppcls/loss/celoss.py)训练, 为了获得更加鲁棒的特征,后续会使用其他Loss参与训练,敬请期待。
+
+全部的超参数及具体配置:[ResNet50_vd_Aliproduct.yaml](../../../ppcls/configs/Products/ResNet50_vd_Aliproduct.yaml)
+
+
+## 2 Inshop
+
+### 1 数据集
+
+
+
+Inshop数据集是DeepFashion的子集,其是香港中文大学开放的一个large-scale服装数据集,Inshop数据集是其中服装检索数据集,涵盖了大量买家秀的服装。相关数据介绍参考[原论文](https://openaccess.thecvf.com/content_cvpr_2016/papers/Liu_DeepFashion_Powering_Robust_CVPR_2016_paper.pdf)。
+
+### 2 图像预处理
+
+数据增强是训练大规模
+- 图像`Resize`到224x224
+- 图像`RandomFlip`
+- Normlize:图像归一化
+- [RandomErasing](https://arxiv.org/pdf/1708.04896v2.pdf)
+
+### 3 Backbone的具体设置
+
+具体是用`ResNet50_vd`作为backbone,主要做了如下修改:
+
+ - 使用ImageNet预训练模型
+
+ - 在GAP后、分类层前加入一个512维的embedding FC层,没有做BatchNorm和激活。
+
+ - 分类层采用[Arcmargin Head](../../../ppcls/arch/gears/arcmargin.py),具体原理可参考[原论文](https://arxiv.org/pdf/1801.07698.pdf)。
+
+### 4 Loss的设置
+
+在Inshop商品识别中,使用了[CELoss](../../../ppcls/loss/celoss.py)和[TripletLossV2](../../../ppcls/loss/triplet.py)联合训练。
+
+全部的超参数及具体配置:[ResNet50_vd_Inshop.yaml](../../../ppcls/configs/Products/ResNet50_vd_Inshop.yaml)
